Hi all,
I fix my problem!
When I pass a class to a function, as I
load the class via gSystem->Load("libMyClass.so");, I need to do a forward
declaration of MyClass just before the function description, since it
stays normally before the body of the main macro.
Sorry. Mine was a deleted alarm!
Cheers, Tommaso
